PortServer TS incorporates Digi RealPort software, which provides local serial port functionality as well as incoming and outgoing Rlogin and Telnet sessions on each port. The Digi Port Authority - Remote (DPA-Remote) gives PortServer TS users a management tool for monitoring network and serial activity from a Windows or UNIX-based client or server.

In addition, the PortServer TS provides SSH v2 encryption to protect against unauthorized monitoring of LAN traffic and port buffering which can be used to capture vital information from the serial ports of managed UNIX servers for problem resolution.
